A Sister and a Home in Another World

Thanks for asking. I'm in another world, with a sister and a house, and both my parents are dead. Unfortunately, I'm useless, but luckily, my sister has my back... Then one day, I suddenly seemed to get smarter. Everyone says I'm pretending to be a pig to eat the tiger, but I'm not... I'm not... I really did get smarter.
